NIACHINE FOR PITCHING CASKS.

SPECIFICATION forming part of Letters Patent No. 357,323, dated February 8. 1887.

Application filed November 18. 1885. Serial No, 183.158. (No model.)

To all whom it may concern:

Be it known that I, THEODORE KRAUSCH, of North Evanston, in the countyof Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Pitching Casks, of which the following is a specification. I

This inventionrelates to an improved pitching-machine, by which a hot blast can be apro plied to or withdrawn from the interior of the casks, the temperature of the blast be accurately controlled, and any foreign substances excluded from the same; and the invention consists of certain details of construction, as hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents a sideelevation of my improved pitchingmachine, shown as connected to a cash. I Fig. 2 is a vertical longitudinal section of the pitching'machine; and Figs. 3 and at are horizontal sections, respectively, on lines as x and y y, Fig. 2.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents a furnace, which is preferably made in square shape and composed of an exterior shell ofcast-iron plates bolted together and of an interior lining of firebricks or other suitable refractory material. 0 The supporting-feet a of the furnace are cast integral with the side plates, and united by strong connecting bolts a, as shown in Fig. 2. On the connecting-bolts a the grate-bars b are supported.

At one side of the'fu'rnace A is arranged a fire-door, I), through which the fuel is supplied to the interior of the furnace without interrupting the working of'the machine. At the opposite side is arranged a blast-pipe, B, 0 which is specially designed for the purpose of supplying the required blast for casks of large size, while at the remainingsides shorter blast-pipes, O O, are arranged, for the purpose of supplying the blast for smaller kegs.

- At the upper part of the furnaceis supported a detachable shell, A, within which is arranged a steam-coil, D, that is connected at the lower part with a steam-pipe, E, by which the steam is conducted from a boiler of the pitching-ma- 50 chine. The steam-pipe E is provided with a stop-cock and waste-pipe (not shown in the drawings) for the water of condensation. The steam-pipe E is arranged in tiers, one above the other, with a view of economizing space and exposing as large a surface of pipes to the heat of the furnace as possible, the lower tier of serpentine pipes being arranged in one direction, while the next or alternate tier is ar' ranged transversely to the lower tier, and so on, as shown clearly in Figs. 2 and 3.

The steam in the coil D is exposed to the heat of the products of combustion that are drawn upward and around the same to the chimney A at the top of the shell A, the required degree of draft being kept up by a pipe, E, that is branchedoff from the pipe E.

The upper end of the steam-coil Dbranches out into as many branch pipesf as there are hot-blast pipes B and O, which branch pipes are conducted through the walls or the shell A and through the blast-pipes B and 0, being connected with steam -jet pipesf in the same. The steam-j et pipesf are arranged in line with the axes of the blast-pipes B and O, which are provided with nozzles B and 0, having ejection-openings in the ends and sides. The branch pipes f, that conduct the steam from the heatingcoil D'to the pipes B and O, are providedat their vertical portion, outside of the furnace, with stop-cocks), for letting on, regulating,and shutti ngoii'the supply of steam to the blast-pipes.

Wherever a boiler is located near the pitching-machines,the steam-pipe may be connected directly to the jet-pipes in the blast-pipes; but in most cases it is preferable to arrange a coil in the furnace for heating the steam to a higher temperature.

The nozzles B or G are introduced into the casks or kegs, as the case maybe, after which steam is admitted to the steam-jet pipes f. The escaping steam exerts a suction on the fire-gases in the furnace and forces ahot blast of high temperature at high pressure into the casks or kegs, the firegases andsteam melting the coat of pitch at the interior of the casks and removing all the impurities deposited in the same. The melted pitch and the dissolved impurities are ejected through the open space around the nozzles to the outside, so as to impinge against fixed guard-shields G, that are rigidly attached at some distance from the noz- I zles to the blast-pipes G and B, respectively. The shields G serve for deflecting the flame and impurities, so as to prevent their being spattered over the pitching apparatus.

Vhen small kegs only are to be heated preparatory to pitching, the large blast-pipe B is preferably removed and the opening by which it is connected to the furnace closed by an iron cap. The nozzle 18 of the large blast-pipe B is downwardly bent at the end, for the purpose of ejecting the gas and steam mixture at the bottom of the cash, where the melted pitch mostly congrcgates, so that the, same is scattered over the interior surface of the cash and finally ejected through the space around the nozzle.

The advantages of my improved pitching machine are that the steam is supplied to the cash together with the hot air or firegases from the furnace and injected into the same with considerable force. The united action of the heated steam and the hot gases from the furnace melts instantly the coating of pitch at the interior of the cask and cleans the same thoroughly in a quick and effective manner. The pressure of the hot blast ejects the melted pitch, ashes, cinders, and other foreign substances that were deposited in the cash or carried into the same by the blast.

The fire is kept up without interruption throughout the operation of the apparatus, so that the cleaning and heating of the casks can he carried on continuously, preparatory to the introduction of a new quantity of pitch.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with the 'blastfurnace having a blast-pipe extending therefrom, of a steam heating-coil in the upper part of said furnace, an induction-pipe leading thereto, a branch from said steam-induction pipe discharging upwardly in the exhaust-flue of said furnace for producing a draft therein, and an eduction-pipe leading from said coil to the interior of said blast-pipe and provided with a jet near the interior of the nozzle thereof, as and for the purpose set forth.

2. The combination, with a furnace having a number of blastpipes of different sizes extending therefrom, of a steam heating-coil in, the upper part of said furnace, an inductionpipe leading thereto, a branch from said steaminduction pipe discharging upwardly in. the cxhaustflue of said furnace for producing a draft therein, and eduction-pipes leading from said coil to the interior of said blast-pipes and provided with jets near the interior of the nozzles, as and for the purpose set forth.

3. The combination,with a furnace having a number of blast-pipes of difi'crentsizcs extending therefrom, of a steam heatingcoil in the upper part of said furnace and an inductionpipe leading thereto, abranch from said steaminduction pipe discharging upwardly in the exhaust-flue of said furnace for producing a draft therein, and eduction-pipes leading from said coil to the interior of said blast-pipes and provided with jets near the interior of the nozzles thereof, said steam induction, eduction, and branch pipes being provided with cocks, as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed my name in pres ence of two subscribing witnesses.

THEODORE KRAUSCH.
